The Variability of Fraus simulans

The more I become involved in the study of Australia's moths, the more fascinated I become.

Variability between species, such as the Geometrid, Ciampa arietaria has caused some confusion to this little moth-er in the past! This one's a doozy for playing with your head until you learn the giveaway characteristics of Ciampa arietaria.

Size within the same species has been fascinating too. Some caterpillars are better feeders than others, apparently!

Now we come to the complex world of the Hepialid.

I was recently asked to take Hepialid specimens for identification purposes. Of the 10 Fraus specimens I provided, I thought/hoped at least a couple would not be Fraus simulans!

The jury is back and bang goes the gavel. They were all Fraus simulans!

Well, that's it for the variability of Fraus simulans - now for something completely different.

THE MISSION

If I am able to learn one new thing each day in the vast field of entomology, I shall be content.Since I began this Blog, I believe I am achieving my mission.Memo to experienced entomologists:If you find an incorrect identification, could you please set the record straight! All comments will be published and you will be aiding me in my pursuit of knowledge!

Lepidoptera

This site is a diary of sorts as an ongoing record of butterflies and moths found in my area of Victoria, Australia, but I will also include other insects.I became interested in butterflies and moths in 2005. In June last year, I decided to undertake a long-term lay study into populations, nectar and larvae host plants, specifically for butterflies but the odd moth is getting in on the act!Unfortunately, I've noted a decline in butterfly populations in and around my garden over the past two years.In 2005, common species such as the Australian Painted Lady (Vanessa kershawi) and the Caper White (Belenois java) were in large numbers. I noticed a decline in butterfly numbers in 2006.In 2007, they were well down. The Cabbage White (Pieris rapae) may still be recorded as common, but numbers are well down for that butterfly, too.

The Common Grass-blue (Zizina labradus) is well-represented, but by no means prolific this season.

About Me

I am a recently retired small-scale primary producer.
I've been a keen nature (and animal behaviour) observer for most of my life but now I have the time to direct my energy towards learning much more about the fauna and flora around me.
I'm a keen photographer and I credit the invention of digital photography steering me onto the path I am now so enjoying!
